Abstract

Optical non-contact, interferometric measurement strategies for mold pins and plates provide an effective means for improving the consistency of the injection molding of small lenses for consumer devices. In this presentation, we describe high-precision interferometric metrology combined with motion systems and advanced software to address the wide range of length scales and metrology requirements of mold assemblies intended for high-volume production.
